associated to the data of \(¶^1,G,\) . Let \(a\in \)  be such that \(C\)  is the associated spectral curve. Note that we in fact have \(a\in ^{ani}\subset ^{\heartsuit }\) , the locus where the spectral curves are irreducible, resp. reduced (we will not need a more general definition of \(^{ani}\)  or \(^\heartsuit \)  here, for that see [1]}).
